Özet

Two new iridoid glycosides, karsoside [1] and scropolioside D [2), were isolated from the aerial parts of Scrophularia ilwensis. Their structures were elucidated on the basis of chemical and spectral data as 6'-O-(beta-D-xylopyranosyl)-methylcatalpol and 6-0-[(2'',4''-di-O-acetyl-3''-O-trans-cinnamoyl)-alpha-L-rhamnopyranosyl]-catalpol, respectively. Additionally, four known iridoids (aucubin, harpagide, 8-0-acetylharpagide, and ajugol), a phenylpropanoid glycoside (angoroside C), and two flavonoids (quercetin-3-0-rutinoside and kaempferol-3-0-rutinoside) were isolated and identified.
